CMA CGM MAPUTO against its type

Built in 2011, it is 3 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 18,321 gross tonnage it is smaller than 78% of the other 3,000 container ships with a recorded tonnage. It is one of 336 container ships here under the Malta flag, 9.6% of the 3,495 on the register. The same builder is recorded for 101 other vessels here, 74 of them container ships. Its MRV returns name it NEFELI for 2018 and CMA CGM MAPUTO for 2023–2025. The reported port of registry changed: MONROVIA (2018), then VALLETTA (2024–2025).

Its 11,261 t of CO₂ for 2025 is 31% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 311.9 kg CO₂, 43% below the type median of 545.6 kg. It logged 3,331 hours at sea against a median of 3,155 hours for its type that year. 13.2% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 4 years with reported emissions, the highest was 2024 (13,416 t) and the lowest 2023 (824 t). Its efficiency percentile within the type went from 78 in 2024 to 84 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,550 of 1,838 qualifying container ships by EEOI, at the 84th percentile. The dashed line is the type median, 14.2; this vessel reported 30.2.

EEOI divides emissions by transport work, which for this vessel and year was 372,522,990 tonne-miles over 36,104 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 48.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2022, so the series has gaps.

From 2024 to 2025, emissions fell 16.1% while distance sailed fell 16.4%and CO₂ per nautical mile rose 0.4%.That points mainly to how much the vessel sailed, rather than the other.
